Overview
The SLE30 Expert Slot Sensor (sometimes called a fork sensor) comprises an opposed-mode emitter and its receiver inside a single convenient housing.
Opposed-mode sensing is very reliable, and the single self-contained housing provides easy installation, with no sensor alignment required. In addition, the molded-in arrow on the emitter portion of the housing and the slotted design on the receiver portion of the housing show at a glance the position of the beam, simplifying installation placement.
